A senior health official said on Wednesday that China encourages non-governmental organizations' participation in the country's fight against HIV/AIDS.

Wang Longde, China's Vice Minister of Health, made his remarks when attending the opening ceremony of the consultation on social determinants of health in the western pacific region of the World Health Organization.

He said government efforts alone were not enough to fight HIV/AIDS given a population of 1.3 billion people and more NGOs needed to join the fight..

On March 1, China started implementing the Guidelines for HIV/AIDS Prevention and Control, displaying the determination of the government to fight the problem. The government has been involved in promoting the use of condoms, needle exchange centers and Methadone treatment for drug users.

With regards to sexually transmitted diseases NGOs were well-established and known to people so they had advantages in HIV/AIDS intervention and prevention control, Wang said.

According to statistics from the Ministry of Health 44.3 percent of HIV/AIDS patients were infected through drug use and 43.6 percent through sexual contact.

China has seen the growth of the role of NGOs in HIV/AIDS prevention and control work in recent years. Several volunteer groups dedicated to AIDS prevention among homosexuals in Beijing, Shanghai, Guangzhou and Chongqing have been set up.

For example, the China Rainbow Organization, based in Chongqing, plays an important role in preventing the spread of HIV among homosexuals with financial help from the British Barry & Martin Trust Fund.

Wang said earlier this month that China is set to improve its AIDS intervention in the country's high-risk groups including sex workers, drug users, homosexuals and their partners.

China has an estimated 650,000 known HIV/AIDS cases with 75,000 known AIDS sufferers according to the findings of a study released by China's health ministry, the World Health Organization and UNAIDS in January.
